Distal Femoral Cut
Warning: The pelvis must remain immobile
during the femoral registration.
Do not perform the femoral registration by
moving the leg in a uniaxial direction, i.e. only in
a flexion/extension, abduction/adduction and/
or combination of both motions (e.g. T-shape).
1. Install the femoral adjustment mechanism on the
anterior side of the femoral reference by aligning
the arrows.
2. Insert the two long pegs of the femoral A/P slider
into the femoral adjustment mechanism.
3. Slide the femoral adjustment mechanism down
towards the distal condyles to the half way mark.

4. Follow the feedback (red and green LEDs) on the
pod attached to the femoral distal cut guide and
adjust flexion/extension and varus/valgus using
the gold and green screws respectively.
Warning: The knee should be flexed between
45 and 80 degrees in order for the system to be
able to compute angle values.
Whenever using the 3.5 mm hex head knob,
remove the knob before performing the cut.
